Introduction BBG-1022-FS-DSP Functional Description

BBG-1022-FS-DSP Functional Description

Figure 1-1 shows a functional block diagram of the BBG-1022-FS-DSP. The

BBG-1022-FS-DSP includes AES/analog audio support and CVBS video I/O.

In addition to a basic signal presence input failover function, a Quality Check

option allows failover to alternate inputs or other actions based on

user-configurable criteria such as black or frozen frame. Frame sync and full

up-down-cross conversion can be added as options.

The BBG-1022-FS-DSP provides a DSP-based platform that supports

multiple audio DSP options. When optioned with various diverse audio

processing options, the DSP-based processing core (which supports numerous

simultaneous processing engines) uses license “credits” which allows flexible

tailoring of multiple proc function instances.

Note: The BBG-1022-FS-DSP DSP base adds support for various DSP audio

options. Specific individual DSP user assets (such as loudness processing,

upmixing, and Dolby encoders) are activated for use only when

corresponding option licenses also reside on the device.

BBG-1022-FS-DSP Input/Output Formats

The BBG-1022-FS-DSP provides the following inputs and outputs:

• Inputs:

• 3G/HD/SD SDI IN A thru SDI IN D – four 3G/HD/SD-SDI inputs.

SDI IN A or SDI IN B can be set to failover to A or B in absence of

opposite channel of this pair.

• CVBS IN – CVBS coaxial analog video input.

• AES IN – BNC (AES-3id, 75Ω) ports as AES input (number of

ports dependent on model).

• AN-AUD IN – Four balanced analog audio embed inputs.

• Outputs:

• 3G/HD/SD-SDI OUT (1-4) – four 3G/HD/SD-SDI buffered video

outputs. Each output can be independently set as processed output

video or selected input video reclocked.

• AES OUT – BNC (AES-3id, 75Ω) ports as AES outputs (number of

ports dependent on model).

• AN-AUD OUT – Four balanced analog audio de-embed outputs.

• CVBS OUT – CVBS coaxial analog video usable with SD video

streams.

Introduction BBG-1022-FS-DSP Functional Description

Video Processor Description

The BBG-1022-FS-DSP video subsystem provides the functions described

below.

Input Video Select/Quality Check Functions

A GUI-based control allows the device to select from up to four 3G/HD/

SD-SDI inputs, and a SD CVBS analog video input. For analog inputs,

waveform-based ancillary data is preserved for extraction and usage later in

the device processing chain.

The input can be selected using DashBoard manual control, set to failover to

an alternate input upon loss of the target input, and can be externally selected

via a GPIO interface. An input

Allowed Rasters and Allowed Frame Rates filter

allows inputs to be filtered (screened) for only user-allowed raster sizes and

frame rates, with unallowed raster/rates being rejected as an input (input

unlock). Reclocked copies of any SDI input can be outputted by the device

when selected as a choice on the output crosspoint.

(Option +QC). Quality Check allows criteria such as black/

frozen frame events to propagate an event alert. This alert can be used by the

Event Setup/actions function to invoke video routing changes, GPO, and

other actions.

Video Output Crosspoint

A four-output video matrix crosspoint allows independently applying the

processed video output or reclocked input to any of the four discrete coaxial

outputs (

SDI OUT 1 thru SDI OUT 4). For an SD output, a CVBS coaxial output

is available as a processed video output.

Timecode Processor

(See Figure 1-2.) This function provides for extraction of timecode data from

input video source, and in turn allow individual timecode strings to be

embedded into the output video. The function can monitor any of the video

inputs for supported timecode formats such as ATC_LTC or ATC_VITC for

down-conversions to HD, and ATC_VITC or VITC waveform (with

selectable odd/even field line number control) for SD SDI or CVBS inputs.

Waveform VITC timecode can also be extracted from a reference input and

used as the output timecode value. If the preferred format is detected, the

preferred format is used by the device; if the preferred format is not detected,

the device uses other formats (where available) as desired. An

internally-generated free-run timecode can be also be embedded on output

video if desired.

The function also provides conversion between various timecode formats and

provides independent insertion and line number controls for each SDI

timecode output format.

When licensed with option

+LTC, this function also can

receive, send and translate between audio/RS-485 LTC timecode formats and

the VBI formats described above.

1 BBG-1022-FS-DSP Functional Description

1-8 BBG-1022-FS-DSP PRODUCT MANUAL BBG-1022-FS-DSP-OM (V1.1)

Figure 1-2 Timecode Processor

Frame Sync Function

Option +FS provides for frame sync control using an external looping

reference signal, or the input video as a frame sync reference.

This function also allows horizontal and/or vertical offset to be added

between the output video and the frame sync reference.

Frame sync can select from either the external frame reference source, or

free-run input video sync. Selectable failover allows alternate reference

selection should the initial reference source become unavailable or invalid. In

the event of input video loss of signal, the output can be set to disable video,

go to black, go to an internal test signal generator pattern, or freeze to the last

intact frame (last frame having valid SAV and EAV codes).

An internal test signal generator provides a selection of various standard

patterns such as color bars, sweep patterns, and other technical patterns. The

test patterns can be applied to the output video upon loss of input or manually

inserted at any time.

Introduction BBG-1022-FS-DSP Functional Description

Video Quality Events Detect Function

Option +QC provides a Video Quality Events user interface and an Event

Triggers

user interface for setting an area of concern across the program raster

which can be monitored for frozen or black video events. Threshold controls

allow setting the sensitivity of the function, while engage and disengage

threshold timing controls allow setting how fast the event detection engages

and releases when triggered. The

Event Triggers user interface allows

instructing the device as to the action to take upon an event (such as go to a

changed signal routing, activate a GPO, send an automated email, or go to a

user-defined preset).

An

Event Triggers user interface can detect Closed Caption Presence and

Closed Caption Absence events. The

Event Triggers user interface in turn

allows instructing the device as to the action to take upon an event (such as go

to a changed signal routing, activate a GPO, send an automated email, or go to

a user-defined preset).

Wings Insertion

Wings insertion allows a symmetrical L-R wings insertion to be integrated

into the program video output. Wings video is accommodated using a

separate wings SDI input. The wings user interface displays wings timing

relative to the output video, allowing wings timing offset to be adjusted such

that wings can be properly framed. (This function does not provide timing

offset control of the wings video; offset must be provided by a external frame

sync card or device controlling the wings video feed.)

The wings L/R insertion width can be manually configured using a wings

width control.

Key/Fill Insertion

Option +KEYER provides for three of the device SDI video inputs to be used

as respective program video, key, and fill inputs. This function provides

chroma keying using the

KEY VID IN signal. The FILL VID IN signal provides

the fill video that is inserted in the area “cleared out” by the key. The keying

user interface displays key and fill timing relative to the output video,

allowing timing offset to be adjusted such that key and fill can be properly

framed. (The option and its host BBG-1022-FS-DSP does not provide timing

offset control of the key/fill video; offset must be provided by external frame

sync cards or devices controlling the key and fill video feed.) The program

video input when using keying accommodates either an SDI or an analog

video input; key and fill inputs are SDI only.

Alpha threshold keyer modes allow full-color key/fill from cost-effective

generic sources such as a standard PC (with appropriate HDMI-to-SDI output

conversion) hosting simple .bmp, .jpeg, or .png graphic files. In these modes,

a common key/fill SDI input provides both the key and fill input.

1 BBG-1022-FS-DSP Functional Description

1-10 BBG-1022-FS-DSP PRODUCT MANUAL BBG-1022-FS-DSP-OM (V1.1)

Color Corrector

Option +COLOR converts the YCbCr SDI input video to the 4:4:4 RGB color

space (where the color correction is applied), and then back to YCbCr SDI on

the output. Controls are available to adjust each RGB level independently for

both white levels (gain) and black levels (offset). Gamma can also be

independently adjusted for each RGB channels. Various controls can be

ganged to provide adjustment for all three color channels simultaneously.

Character Burn-in Functions

User text, video format, and timecode (as selected using the timecode

function) can be burned into the output video. Burn-in attributes such as size,

position, background, color, and opacity are user-configurable. Two discrete

character burn strings can be inserted on output video, with each string

inserted as static text and/or insert only upon LOS. A moving-box insertion

can be enabled to serve as a dynamic raster confidence check even in cases

where the input video image is static or lost.

Trouble Slate Insertion Function

Option +T-SLATE provides for graphic insertion onto the SDI processed

output raster. The function allows for uploading a .png image graphic file to

the card/device memory. (png files are converted to a special format using a

web tool before uploading to the host card/device; this is described in the

setup/operating instructions later in this supplement.)

When the image file(s) is uploaded to the card, its insertion can be enabled via

DashBoard Event Setup controls that enable the graphic insertion only under

certain conditions as desired. (For example, a trouble slate graphic can be set

to insert upon detected input Loss of Signal (LOS).

The trouble slate

function allows for positioning the image within the active

video using DashBoard controls. Refer to +LOGO / +T-SLATE Manual

Supplement OPT-SW-PHXLTS-MS for detailed information and installation/

setup instructions.

Ancillary Data Processor

Option +ANC provides full VANC/HANC ancillary data de-embedding and

embedding for 3G/HD/SD-SDI streams. Direct access to DID and SDID

locations allows extraction or insertion of user data such as camera PTZ,

SCTE 104, closed-captioning read/insert, GPI/GPO via ANC, or other

specialized user payloads. Data can be extracted and inserted within the

device (Bridge mode), or inserted and/or extracted to and from the device via

serial or IP interfaces connecting to external devices/systems.

BBG-1022-FS-DSP-OM (V1.1) BBG-1022-FS-DSP PRODUCT MANUAL 1-11

Introduction BBG-1022-FS-DSP Functional Description

Audio Processor Description

The audio processor operates as an internal audio router. This function

chooses from the following inputs:

• 16 channels of embedded audio from the SDI video input (default

1-to-1 routing to SDI output)

• Up to 16 channels (8 pairs) of discrete AES input

1

• Up to 4 channels of balanced analog audio input

(See Figure 1-3.) The audio processing subsection is built around an internal

16-channel audio bus. This 16-channel bus receives inputs from an input

routing crosspoint that routes de-embedded, and discrete AES and analog

audio inputs, over the 16-channel internal bus. Correspondingly, at the output

end of the 16-channel bus is an output routing crosspoint that in turn

distributes the 16-channel bus signals to embedded, and discrete AES and

analog audio outputs.

An Input Audio Status display shows the presence and peak level of each

input audio channel received by the device. In addition to SDI embedded

audio channel sources, analog and coaxial AES inputs are available as input

audio choices. For AES audio inputs, payload is identified (PCM or data such

as Dolby

®

Digital or E). Each AES input pair has independent sample rate

converters to align each input pair with video timing to accommodate cases

where AES audio is not synchronous with input video (SRC automatically

bypassed for non-PCM payloads). As such, the audio subsection provides a

full crosspoint between all supported audio inputs and output types.

Clean and Quiet Switching option +CQS allows SDI input

selection to be changed from one source to another while ducking audio

during controlled input video switching transitions to provide silence between

input switches. The cross-fade is queued for the next available RP168 switch

line following the switch command.

Note: • Clean audio switching is assured only for intentional, controlled switches via

user control. Clean audio switching cannot be assured for failover switches.

• Clean switching requires that both SDI signals (switch from and switch to)

be stable and present, and of the same SDI format and rate.

• Clean audio switching function is designed for PCM audio. This function

does not assure clean decoded audio when switching from/to Dolby or other

non-PCM audio.

Audio Down Mix Function

(See Figure 1-4.) The Audio Down Mixer function provides for the selection

of any five embedded channels serving as Left (

L), Right (R), Center (C), Left

Surround (

Ls), and Right Surround (Rs) individual signals to be multiplexed

into stereo pair Down Mix Left (

DM-L) and Down Mix Right (DM-R). The

resulting stereo pair

DM-L and DM-R can in turn be routed to any embedded

audio pair as desired (or de-embedded to an AES or analog audio output).

Flex Buses

For both input and output nodes before and after the internal buses, flex buses

provide flexible-structure mixer in which any of 16 summing nodes (

Flex Mix

Bus A

thru Flex Mix Bus P) can receive any device audio input, thereby

allowing several customizable mixing schemes. Similarly, any of the 16

internal bus signals can be applied to an output flex bus mixer.

Audio DSP Function

The Audio DSP Function provides a DSP-based platform that supports

multiple audio DSP options. When optioned with various diverse audio

processing options, the DSP-based processing core (which supports numerous

simultaneous processing engines) uses license “credits” which allows flexible

tailoring of multiple proc function instances. Audio proc options include

Introduction BBG-1022-FS-DSP Functional Description

(See Figure 1-5) The Audio DSP block is positioned between all device audio

inputs (input mixer positioning) as well as audio outputs (output mixer

positioning). Actual audio DSP proc functions are facilitated using licenses

for these options. When any audio option is licensed (activated), the

processing can be positioned at the input or output mixer as desired.

• Input Mixer path positioning locates the DSP pipeline to receive basic

external inputs coming into the device, and then allows DSP

processed output channels to be directed to the internal Audio Bus

channels by selecting Audio DSP channels as sources for destination

Audio Bus channels via the Input Audio Routing/Controls

• Output Mixer path positioning locates the DSP pipeline to receive

Audio Bus channels and then place the DSP processed output

channels directly at the device audio outputs as sources for

destination Embedded Output or AES Output channels via the Output

Audio Routing/Controls.

Limit function can be set to provide absolute peak limiting. This

function is also configurable for aggressiveness. An intelligent

Speech Percentage detection algorithm can help distinguish between

program speech and other sounds. This can help in “fine tuning”

various parameters to best suit the program material.

Text-To-Speech

Cobalt Digital +TTS is a complete 21CVAA digital text-to-speech generation /

audio insertion solution for embedded and discrete audio systems.

+TTS is

available as a software option for new BBG-1022-FS-DSP units. For field

upgrade, the unit must be returned to the factory for option installation.

+TTS interfaces with industry standard Windows Share folder systems to

receive non-proprietary text, XML, or similar plain text files, and converts

and inserts realistic human-voice audio into user-configured audio channels

(typically an SAP channel pair intended for this playout).

+TTS allows for

prioritization based on the organization's discretion (for example, severe

weather alerts out-prioritizing school closings). Alert tones are inserted over

the main program channels to alert the visually impaired that emergency

content is to occur on the SAP channel. Alerts can be played a configurable

number of times, and alerts with higher priority can interrupt current lists for

breaking news. Once the interrupt message is broadcast,

+TTS automatically

reverts to normal audio programming. Refer to +TTS Manual Supplement

OPT-TTS-MS for detailed information and installation/setup instructions.

EAS Text Crawl Generation Option +EAS provides for

automated keying Emergency Alert System (EAS) text crawls in the active

program video output. The function receives its text stream via a device serial

data input. The EAS crawl start can be set to trigger upon receiving the serial

data message, or be set to use a GPI to trigger start of the EAS crawl.

Embedded in the received serial data are commands which set the message

severity to be shown by the keyed crawl (severity is correlated to

user-specified text color and background color for the crawl). User controls

allow control of the crawl speed and repeat of the crawl burn-in (if desired).

Refer to +EAS Manual Supplement OPT-SW-PHXEAS-MS for detailed

information and installation/setup instructions. This supplement is available

as a download on the Products Download page/tab on the product web page.

Audio Events Detect Function

Option +QC provides a Audio Detect Events user interface and an Event

Triggers

user interface for checking user-selected channels to detect audio

silence conditions. The

Event Triggers user interface in turn allows instructing

the device as to the action to take upon an event (such as go to a changed

signal routing, activate a GPO, send an automated email, or go to a

user-defined preset).

BBG-1022-FS-DSP-OM (V1.1) BBG-1022-FS-DSP PRODUCT MANUAL 1-15

Introduction BBG-1022-FS-DSP Functional Description

Control and Data Input/Output Interfaces

GPI Interface

Two independent ground-closure sensing GPI inputs (GPI 1 and GPI 2; each

sharing common ground connection as chassis potential) are available.

Associated with each GPI user control is a selection of one of 32 user-defined

presets in which GPI activation invokes a control preset.

Because the GPI closure invokes a user-defined preset, the resulting setup is

highly flexible and totally user-defined. Invoking a user preset to effect a

change involves device setup communication limited only to the items being

changed.

GPI triggering can be user selected to consider the activity on discrete GPI

ports, or combinations of logic states considering both GPI inputs, as well as

be set for level or edge triggering. This flexibility allows multistage,

progressive actions to be invoked if desired. Indication is provided showing

whenever a GPI input has been invoked.

GPO Interface

Two independent phototransistor non-referenced (floating) contact pairs

(

GPO 1/1 and GPO 2/2) are available. A GPO can be invoked by setting a GPO

to be enabled when a preset is in turn applied (i.e., when a preset is invoked

(either manually or via event-based loading), the GPO is correspondingly also

activated.

Serial (COMM) Ports

The BBG-1022-FS-DSP is equipped with two, 3-wire serial ports (COM 1 -

Serial Port 1, COM 2 - Serial Port 2). The ports provide for SMPTE 2020

de-embedding to an output port, and provide RS-485 LTC I/O (when licensed

with option

+LTC). Either port can be configured as RS-232 Tx/Rx or RS-422

non-duplexed Tx or Rx.

+SCTE104 Insertion

Option +SCTE104 provides generation and insertion of SCTE 104 messages

into baseband SDI. Message send can be triggered from automation GPI or

other event action modes. The option can also execute actions based on SCTE

104 messages received by the device, as well as send triggered SCTE 104

packets to other downstream systems.

The user interface is based on common SCTE 104 operations: Splice Start

Normal, Splice Start Intermediate, Splice End Normal, Splice End

Intermediate, and Splice Cancel (splice_request_data variants), offering full

control of splice start, end, and cancel as well as pre-roll and break duration

offsets. (A Manual Supplement is planned for this option. Please check

product web page.)

Alarm Function

The device can be set to monitor input video/audio for input errors such as

input LOS, frozen or black frame, loss of reference, closed captioning

ancillary data loss, and/or per-channel audio absences. These alarms can be

propagated as a device general error or warning message, and can be

downloaded as basic .txt logs or via a Syslog function.

User setup tables configure the alarm severity escalation as well as trigger

holdoff/release and other thresholds as applicable.

User Control Interface

BBG-1022-FS-DSP uses an HTML5 internal web server for control/

monitoring communication, which allows control via a web interface with no

special or unique application on the client device. Connection to the device to

the network media connection is via a standard 10/100/1000 RJ-45 Ethernet

connection. The device can also be controlled using DashBoard™ remote

control, where it appears as a frame connection.
